Load cuXfilter dataframe

cux_df = cuXfilter.DataFrame.from_arrow('/home/ajay/data/146M_predictions_v2.arrow')

Define Charts

chart0 = charts.bokeh.choropleth(x='zip', y='delinquency_12_prediction', aggregate_fn='mean',

chart3 = charts.panel_widgets.range_slider('borrower_credit_score',data_points=50,width=400, height=400)

Add mappings for chart1

mapper1 = {}

    mapper1[int(val)] = 'l_'+str(val)

chart1 = charts.panel_widgets.multi_select('dti', width=400, height=400, label_map=mapper1)
#also available: panel_widgets.dropdown

Create dashboard

d = cux_df.dashboard([chart0, chart1], layout=layout_1, title="Ajay's Dashboard")
